Not Working: MasterTableView.GetItems(GridItemType.Header)

The function is returning no items. Following is a copy of my markup and code:

protected void Page_Load(object sender, EventArgs e)

{

RadGrid1.DataSource = GetDataSource();

RadGrid1.DataBind();

}

private DataTable GetDataSource()

{

...

}

private void AddGroupHeadersToGrid()

{

GridItem[] header = RadGrid1.MasterTableView.GetItems(GridItemType.Header);

//GridTHead head = ((GridTHead)header[0].Parent.Controls[0].Parent);

GridHeaderItem newHeaderItem = new GridHeaderItem(RadGrid1.MasterTableView, 0, 0);

newHeaderItem.Cells.Add(new GridTableHeaderCell());

newHeaderItem.Cells[0].Text = "I'm a header.";

//head.Controls.AddAt(0, newHeaderItem);

}

protected void RadGrid1_PreRender(object sender, EventArgs e)

{

AddGroupHeadersToGrid();

}

The markup looks like this:

<telerik:RadGrid ID="RadGrid1" runat="server" AutoGenerateColumns="false"

onprerender="RadGrid1_PreRender">

<MasterTableView>

<Columns>

<telerik:GridBoundColumn HeaderText="Question" DataField="Question" UniqueName="Question">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn HeaderText="Score" DataField="MTDScore" UniqueName="MTDScore">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn HeaderText="Area" DataField="MTDArea" UniqueName="MTDArea">

<telerik:GridBoundColumn HeaderText="Score" DataField="QTDScore" UniqueName="QTDScore">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn HeaderText="Area" DataField="QTDArea" UniqueName="QTDArea">

<telerik:GridBoundColumn HeaderText="Score" DataField="YTDScore" UniqueName="YTDScore">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn HeaderText="Area" DataField="YTDArea" UniqueName="YTDArea">

</Columns>

</MasterTableView>

</telerik:RadGrid>

I would really appreciate if somebody can tell me what I'm doing wrong here!

$find not working with IE 8

Hi,

I am trying to reference a radTextBox through javascript to capitalize its value on blur and keypress event.
However, $find(client-Side-Object-Name) returns null in IE whereas it works fine in firefox (3.5.5).

The version of our telerik is 2008.3.1314.35

    
            <telerik:RadScriptBlock ID="radScriptBlock" runat="server"> 
        
                <script type="text/javascript"> 
        
                    AddPageLoadHandler(function() 
        
                    { 
        
                        AutoCapitaliseFirstChar('<%= FirstNameTextBox.ClientID %>'); 
        
                    }); 
        
                </script> 
        
                </telerik:RadScriptBlock>

    
            function AddPageLoadHandler(fn) 
        
            { 
        
                Sys.WebForms.PageRequestManager.getInstance().add_pageLoaded(fn); 
        
            }

    
            // not created dynamically 
        
            <telerik:RadTextBox runat="server" ID="FirstNameTextBox" />

    
            // These client-side functions auto-capitalises text in RadTextBox as user enters it 
        
            // The conversion is done after a short timeout to avoid interfering with normal onfocus behaviour 
        
            function AutoCapitaliseFirstChar(radTextBoxClientId) { 
        
                var radTextBoxClientObject = $find(radTextBoxClientId); 
        
                // here radTextBoxClientObject is null for IE but not for firefox 
        
                // so it works fine with firefox not with IE 8 
        
                // This converts the text when field loses focus 
        
                $(radTextBoxClientObject.get_element()).blur(function() { 
        
                    setTimeout(function() { 
        
                        var val = radTextBoxClientObject.get_value(); 
        
                        radTextBoxClientObject.set_value(val.substring(0, 1).toUpperCase() + val.substring(1)) 
        
                    }, 200); 
        
                }); 
        
                // Except in Safari, convert the text as it is typed 
        
                // (in Safari this is incompatible with the field autocomplete behaviour) 
        
                if (!$.browser.safari) { 
        
                    $(radTextBoxClientObject._textBoxElement).keypress(function() { 
        
                        setTimeout(function() { 
        
                            var val = $(radTextBoxClientObject._textBoxElement).val(); 
        
                            radTextBoxClientObject.set_value(val.substring(0, 1).toUpperCase() + val.substring(1)) 
        
                        }, 200); 
        
                    }); 
        
                } 
        
            }

Any ideas would be appreciated,

regards,

Toby

[Solved] RadDataPager needs OnPageSizeChanged Event handler

For consideration in a future release the RadDataPager should allow registration to an OnPageSizeChanged event. I am handling the databinding and paging in code behind going through a WCF tier; however, I had to remove the change PageSize functionality from the end user because this event doesn't exist.

The Functionality should be like this to mirror the PageIndexChanged event:

ASPX:

   <telerik:RadDataPager ID="RadDataPager1" runat="server" OnPageIndexChanged="RadDataPager1_PageIndexChanged"
   OnTotalRowCountRequest="RadDataPager1_TotalRowCountRequest"
   OnPageSizeChanged="RadDataPager1_PageSizeChanged" Skin="Windows7">
   ...
   </telerik:RadDataPager>

Code Behind:

   protected void RadDataPager1_PageSizeChanged(object sender, RadDataPagerPageSizeChangeEventArgs e)
   {
   int NewPageSize = e.NewPageSize;
...
   }

Cheers,
Andrew.

Load on demand PageViews

Hi,

I have a RadTabStrip linked with a RadMultiPage.

ASPX:

<telerik:RadTabStrip ID="tsConfig" runat="server" MultiPageID="mpConfig" SelectedIndex="0"

Width="100%" Skin="Office2010Silver" OnClientTabSelecting="OnTabSelecting_CheckPageView">

<Tabs>

<telerik:RadTab Text="Tab 1" PageViewID="rpvGeneral" Width="150px">

</telerik:RadTab>

<telerik:RadTab Text="Tab 2" PageViewID="rpvPhoto">

</telerik:RadTab>

<telerik:RadTab Text="Tab 3" PageViewID="rpvListePatients">

</telerik:RadTab>

<telerik:RadTab Text="Tab 4" PageViewID="rpvListesPrescriptions">

</telerik:RadTab>

<telerik:RadTab Text="Tab 5" PageViewID="rpvPrescripteur">

</telerik:RadTab>

</Tabs>

</telerik:RadTabStrip>

<telerik:RadMultiPage ID="mpConfig" runat="server" SelectedIndex="0" Width="100%"

BackColor="White" Height="500px" BorderColor="Silver" Style="overflow: hidden;">

<telerik:RadPageView runat="server" ID="rpvGeneral">

<cgsi:ConfigGeneral runat="server" ID="ucConfigGeneral" />

</telerik:RadPageView>

<telerik:RadPageView runat="server" ID="rpvPhoto" Visible="false">

<cgsi:ConfigPhoto runat="server" ID="ucConfigPhoto" />

</telerik:RadPageView>

<telerik:RadPageView runat="server" ID="rpvListePatients" Visible="false">

<cgsi:ConfigListePatients runat="server" ID="ucConfigListePatients" />

</telerik:RadPageView>

<telerik:RadPageView runat="server" ID="rpvListesPrescriptions" Visible="false">

<cgsi:ConfigListesPrescriptions runat="server" ID="ucConfigListesPrescriptions" />

</telerik:RadPageView>

<telerik:RadPageView runat="server" ID="rpvPrescripteur" Visible="false">

<cgsi:ConfigPrescripteur runat="server" ID="ucConfigPrescripteur" />

</telerik:RadPageView>

</telerik:RadMultiPage>

VB:

Private Sub tsConfig_TabClick(ByVal sender As Object, ByVal e As Telerik.Web.UI.RadTabStripEventArgs) Handles tsConfig.TabClick

e.Tab.PageView.Visible = True

End Sub

My problem is that in the ascx named "ucConfigPrescripteur" I have a RadComboBox that I set the width to 160px. But for some reason, on the page, the combobox is set to 260px until I do a postback it will set it to 160px.

This is only happenning with RadMultiPage.

Thanks.

extra arguments for "telerik events"

Hello,

Is there a way to have events, such as RadDatePicker.ClientEvents.OnDateSelected or RadListBox.OnClientSelectedIndexChanged, handle functions with arguments, apart from "sender" and "eventArgs"?
The following code doesn't do it completely right:

RadListBox rlb = new RadListBox();

rlb.OnClientSelectedIndexChanged = "ToSomething('Aaa', 'Bbb', 'Ccc')";

function DoSomething(a, b, c)

{

//code

}

Thanks in advance.
